ISSUE:
The glow plug relay may melt and result in a no start/hard start condition. This may be caused by the nuts on the glow plug relay losing their torque and
increasing the resistance on the connections of the relay.
ACTION:
Increase the torque of the nuts on the glow plug relay and add a lockwasher. Refer to the following Service Procedure for details.
NOTE:
THIS PROCEDURE SHOULD BE ADHERED TO FOR ALL FUTURE GLOW PLUG REPAIRS ON 7.3L DIT DIESEL ENGINES.
SERVICE PROCEDURE

DO NOT USE A SCREWDRIVER OR SIMILAR TOOL TO PRY OFF THE TERMINAL COVER. BATTERY VOLTAGE IS PRESENT AT
THE TERMINALS.
